CAS 358-23-6 — Trifluormethansulfonsäureanhydrid (Triflatanhydrid)

Trifluoromethanesulfonic anhydride, or triflic anhydride, is a highly reactive reagent widely used in organic synthesis for introducing trifluoromethanesulfonyl groups, enabling selective fluorination, dehydrations, and activation of carboxylic acids. This colorless to pale yellow liquid is a powerful sulfonylating agent with exceptional stability under anhydrous conditions. Catalogue details: CAS 358-23-6, molecular formula (CF₃SO₂)₂O, molecular weight 282.14 g/mol. Store at ambient temperature in a dry, inert atmosphere. Hazard classification: Danger (corrosive, toxic). Molekula supplies triflic anhydride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
